In Fig. 1

The axle 4 is rigidly secured to the wheel 2 at one of the drawings, thebar 17 is shown with one end restend and projects loosely through thehub of wheel 3 ing between the shoulders 15 and 25 of the ratchet andthrough the attachment. wheel 14 which indicates that the drive wheel 3of the 35 The attachment comprises a drum 5 which is loosely machine isthe one that is actuating the dropping mounted upon the shaft 4 and hasits central portion mechanism, or, in other words, the position whichthe provided with a wide, fiat rib or projection 6 which is part wouldtake if the machine were being turned slotted transversely at 7.

The outer faceof each of the locking bars is provided Loosely mounted upon the shaft4, or upon the hub with a lip or flange 27 upon which is pivotallymounted of the wheel 3, is a similar disk 14 having the shoula dog 28that is adapted to be located within the smooth ders 15 of its flangenormally standing adjacent to the portion of the drum 5 or the cut-awayportion 10 of the ribs 8, with its free end adapted to be engaged by theshoulders or teeth of the ratchet wheels 12 and 1.4. The rear end ofeach dog is provided with a heel or shoulder 29, which is adapted to beheld against the outer face of the locking bar by means of a spring 30,which is adapted to engage with the forward end of the dog and normallyhold it outward in position for engaging with said ratchet wheels. Inthis manner, when there is a sutiicient variation of the rates of speedor travel of the wheels as to cause a shifting of the bar 17 the wheelthat was the slower moving one and is in engagement with the bar 17 willcause the drum 5 to carry the shifting bar, as 19, at the opposite endand the pawl 28 thereon, forward faster than the slower wheel is movinguntil the free end of the pawl engages with one of the shoulders 15 andhas its further forward movement stopped, which will also cause thelocking bar, to which it is pivoted, to stop its forward move ment withthe drum. This will cause the forward end of the bar to he withdrawnfrom the notch 22 and thereby unlock the bar 17 and permit it to bemoved longitudinally by the rounded shoulder 25 of the faster movingwheel 14 into engagement at its other end with the shoulders of theslower moving wheel 12. When the speed of the wheels vary again the sameprocess takes place with the pawl on the bar 18 and the bar 17isunlocked and shifted in theopposite direction. This renders the actionof the device absolutely automatic and requires no attention from theattendant.

Motion from the drum 5 which is transmitted to it by the mechanism asabove described, is transmitted to the dropping mechanism of the machinein any desired manner, preferably by means of a sprocket chain. notshown, and a sprocket wheel 32. which is mounted upon a shell thatsurrounds the drum 5 and ratchet wheels 12 and 14.. The shell is securedto the drum in any desired manner, preferably by means of a screw 34,and the sprocket wheel is secured to the drum, preferably by means ofbolt 35 which pass through cars 36 on the shell and through spokes orinwardly extending projections 37 of the ratchet wheel.

By equipping a corn dropper with the above simple mechanism, it isevident that the usual check wire can be dispensed with by constructingthe wheels of the proper diameter, or by properly proportioning thesprocket wheel on the dropping mechanism in relation to the diameter ofthe sprocket wheel 32. This will save the trouble of having to changethe wire at each side of the field ior each trip of the corn planter,and it will also permit oi the machine being readily turned at the endof each row without the possibility of the mechanism being actuated todrop any corn.

Instead of utilizing the attachment for check row planting, it can beused as well forcontinuous dropping, as from a seed drill. in which casethe attachment would be placed betweenthewheel I, and the drill box andthe axle would bc extended through to the other end of the drill box andthe wheel 2 rigidly connected thereto. When arranged in this manner itis evident that the drill can be turned at each end with one of thewheels standing stationary, as above described, and

the other one moving in a half circle without the drill mechanism beingactuated, no difference whether the drill is turned to the right or tothe left. This avoids the necessity for the person in charge of thedrill actuating any special mechanism for throwing the drill into andout of gear when making the turn at cithcr end.

Although the most desirable form for constructing the parts of theattachment have been shown and do scribed. it is evident that suchchanges in the construction, form, and size of the parts, as come withinlhc scope of the appended claims may bc made without departing from thespirit of the invention.
